[0032] In the field of logistics equipment technology, drive devices are often installed in logistics equipment to transport goods.

[0033] In related technologies, the drive unit includes a drive motor and a belt drive assembly 200 connected to the drive motor. The drive motor drives the movement of goods via the belt drive assembly 200.

[0034] However, due to the lack of overload protection mechanisms in existing drive units, goods exceeding the rated load can easily damage the drive unit.

[0035] To address the aforementioned problems, this application provides a drive device equipped with an overload protection mechanism. The solution provided by this application will be described in detail below with reference to the accompanying drawings.

[0036] Figure 1 This is a schematic diagram of the first overall structure of a drive device with an overload protection mechanism provided in an embodiment of this application; Figure 2 yes Figure 1 A schematic diagram of the second integral structure of the drive unit equipped with an overload protection mechanism; Figure 3 yes Figure 1 The diagram shows the third overall structure of the drive unit equipped with an overload protection mechanism.

[0037] Reference Figures 1 to 3 As shown, this application embodiment provides a drive device with an overload protection mechanism, specifically including a drive component 100, a transmission component 200, a fixed frame 300, an overload protection mechanism 400, and a load component 500.

[0038] The fixed frame 300 serves a supporting function, supporting all components. Specifically, the drive component 100 and the transmission assembly 200 are both fixedly mounted on the fixed frame 300, while the load component 500 is slidably mounted on the fixed frame 300 along its length. For example, the load component 500 can move along the length of the fixed frame 300 via a slide rail assembly. Specifically, the slide rail assembly includes a slide rail and a slider. The slide rail is arranged along the length of the fixed frame 300, and the slider is fixedly mounted on the load component, with the slider engaging with the slide rail.

[0039] The drive unit 100 is connected to the transmission assembly 200. One end of the overload protection mechanism 400 is connected to the transmission assembly 200, and the other end is connected to the load unit 500. The load unit 500 is used to connect with the goods it carries. The drive unit 100 drives the load unit 500 to move through the transmission assembly 200 and the overload protection mechanism 400, thereby moving the goods. When the goods transported by the load unit 500 exceed the specified weight, the overload protection mechanism 400 activates, causing the drive unit 100 to stop in time, preventing damage to the drive unit due to overload. It should be noted that the length direction of the fixing frame 300 can be referenced... Figure 1 The x-direction is shown in the figure.

[0040] For example, the drive component 100 may be a servo motor, a cylinder, or a hydraulic cylinder. The transmission assembly 200 may be a belt drive assembly 200, a chain drive assembly 200, or a transmission screw assembly. The mounting bracket 300 may be a steel plate structure.

[0041] Figure 4 yes Figure 1 A first schematic diagram of a partial assembly of a drive unit equipped with an overload protection mechanism; Figure 5 yes Figure 4 The second schematic diagram shows a portion of the drive unit assembly equipped with an overload protection mechanism.

[0042] Reference Figure 4 and Figure 5 As shown, in some examples, the overload protection mechanism 400 includes a fixed base 410, an elastic member 420, and a detection member 430. The fixed base 410 is fixedly connected to the transmission assembly 200. For example, when the transmission assembly 200 is a belt drive assembly 200, the fixed base 410 is fixedly connected to the drive belt 220; when the transmission assembly 200 is a chain drive assembly 200, the fixed base 410 is fixedly connected to the drive chain.

[0043] Reference Figures 1 to 5As shown, exemplarily, the belt drive assembly 200 includes two drive belts 220, drive belt pulleys 210, and a drive belt 220. The two drive belts 220 and drive belt pulleys 210 are respectively disposed at both ends of the fixed frame 300. One of the drive belts 220 and drive belt pulleys 210 is connected to the output end of the drive component 100 via a coupling. The drive belt 220 is wound around the two drive belts 220 and drive belt pulleys 210, and the fixed seat 410 of the overload protection mechanism 400 is fixedly connected to the drive belt 220.

[0044] In some examples, the load component 500 is slidably connected to the fixed base 410, and the load component 500 is connected to the fixed base 410 via an elastic member 420. Exemplarily, the load component 500 can be slidably connected to the fixed base 410 via a slider rail assembly or via a limiting member slide bar 440 assembly.

[0045] When the load component 500 is slidably connected to the fixed base 410 via the slider-rail assembly, one of the load component 500 and the fixed base 410 is fixedly connected to the slider, and the other is fixedly connected to the rail, with the slider and rail engaging. One end of the elastic component 420 is fixedly connected to the fixed base 410, and the other end is fixedly connected to the load component 500. The fixed base 410 moves the load component 500 through the elastic force of the elastic component 420. When the load transported by the load component 500 exceeds the preset load, the elastic force provided by the elastic component 420 cannot move the load component 500, resulting in deformation, and the fixed base 410 and the load component 500 move relative to each other. For example, the elastic component 420 can be a tension spring.

[0046] Similarly, when the load component 500 is slidably connected to the fixed base 410 via the limiting member slide rod 440 assembly, one of the load component 500 and the fixed base 410 is fixedly connected to the limiting member, and the other is fixedly connected to the slide rod 440, with the limiting member and the slide rod 440 engaging in a cooperative connection. One end of the elastic member 420 is fixedly connected to the fixed base 410, and the other end is fixedly connected to the load component 500.

[0047] The detection component 430 is mounted on either the load component 500 or the fixed base 410. The detection component 430 is used to detect the relative movement between the fixed base 410 and the load component 500. The detection component 430 can be a distance sensor or a photoelectric sensor. If the detection component 430 is a distance sensor, it is mounted on either the load component 500 or the fixed base 410, facing the other. When the detection component 430 detects that the distance between the two exceeds a preset distance, it indicates that relative movement has occurred, and further indicates that the load component 500 is transporting more goods than the preset load. At this point, the drive component 100 stops operating to prevent damage to the entire drive unit due to overload.

[0048] If the detection component 430 is a photoelectric sensor, it can be mounted on either the load component 500 or the fixed base 410, with a through hole on the other component through which the photoelectric signal emitted by the detection component 430 passes. If the weight of the load on the load component 500 is less than the preset load, the distance between the load component 500 and the fixed base 410 remains constant during its movement, allowing the photoelectric signal from the detection component 430 to pass through the through hole. If the weight of the load on the load component 500 is greater than the preset load, the distance between the load component 500 and the fixed base 410 increases during its movement, preventing the photoelectric signal from passing through the through hole. It can be understood that the photoelectric signal from the detection component 430 can be used to determine whether the load on the load component 500 is overloaded.

[0049] Continue to refer to Figure 4 and Figure 5 As shown, in some specific examples, for instance, the overload protection mechanism 400 includes a slide bar 440, one end of which is fixedly connected to the load component 500. The slide bar 440 passes through the fixed base 410, and an elastic component 420 is sleeved on the slide bar 440. The two ends of the elastic component 420 are respectively connected to the fixed base 410 and the load component 500.

[0050] In some other examples, the overload protection mechanism 400 also includes a connector 450. The connector 450 is fixedly connected to the fixed base 410, and a slide rod 440 passes through the connector 450. At least one elastic member 420 is provided on the side of the connector 450 facing away from the load member 500. At least one elastic member 420 is provided between the connector 450 and the load member 500, and all elastic members 420 are sleeved on the slide rod 440. The fixed base 410 drives the load member 500 to move through the connector 450 and the elastic members 420.

[0051] Specifically, the connector 450 includes a fixed plate and a mating plate perpendicular to the fixed plate. The fixed plate is fixedly connected to the fixed seat 410. The slide rod 440 passes through the mating plate. At least one elastic member 420 is provided on each side of the mating plate, and all elastic members 420 are sleeved on the slide rod 440. The elastic members 420 provide elastic force to drive the load member 500 to move. Similarly, when the load member 500 transports goods exceeding the preset load, the elastic members 420 need to deform to generate a greater elastic force to drive the load member 500 to move, thereby increasing the relative distance between the fixed seat 410 and the load member 500. For example, in these examples, the elastic member 420 may be a compression spring.

[0052] In some examples, the detection component 430 is connected to the load component 500, and the detection component 430 is configured as a photoelectric sensor. The connector 450 has an opening perpendicular to the direction of movement of the load component 500, through which the photoelectric signal of the detection component 430 passes. When the load conveyed by the load component 500 exceeds a preset load, and it moves relative to the fixed base 410, the photoelectric signal of the detection component 430 cannot pass through the opening. That is, whether the photoelectric signal emitted by the detection component 430 passes through the opening determines whether there is relative movement between the fixed base 410 and the load component 500, and thus determines whether the load connected to the load component 500 exceeds the load.

[0053] Continue to refer to Figure 4 and Figure 5 As shown, the overload protection mechanism 400 also includes a mounting bracket 460, which is configured in an L-shape. A first end of the mounting bracket 460 is connected to the load component 500, and a second end extends to an opening. A detection component 430 is fixedly mounted at the second end of the mounting bracket 460, and the photoelectric signal emitted by the detection component 430 passes through the opening of the connector 450. In some other examples, the detection component 430 is configured as a slotted photoelectric sensor. The slotted signal transmitting end of the slotted photoelectric sensor is positioned at the opening of the connector 450.
